Also known as solitary bone plasmacytoma or extramedullary plasmacytoma when outside the bone.
Summary
Solitary plasmacytoma is a type of cancer that involves a localized collection of abnormal plasma cells, usually in the bone or soft tissue. When in remission, the disease shows no active signs following treatment.
Causes
The exact cause is unknown, but it can be related to the unchecked growth of plasma cells, potentially triggered by genetic mutations.
Risk Factors
Age: More common in older adults.
Gender: Slightly more prevalent in males.
Family history of plasma cell disorders.
Certain viral infections and weakened immune systems may also contribute.
Symptoms
Localized bone pain or swelling.
Possible fractures if the bone is weakened.
If found in soft tissue, it might present as a mass.
Diagnosis
Imaging tests like MRI or CT scans to locate the plasmacytoma.
Biopsy of the tumor to confirm the diagnosis.
Blood and urine tests to rule out multiple myeloma.
Treatment Options
Radiation therapy is often effective in treating and achieving remission.
Surgery may be an option if the plasmacytoma is in an accessible area.
Regular monitoring to ensure it does not progress into multiple myeloma.
Prognosis and Follow-Up
Remission generally indicates a favorable prognosis but requires continuous follow-up.
Regular check-ups are crucial to detect any signs of the condition returning or evolving into multiple myeloma.
Complications
Potential progression to multiple myeloma if not managed.
Risk of fractures if bone is involved, even during remission.
Lifestyle & Prevention
Maintaining a healthy lifestyle and regular exercise can help strengthen bones and overall health.
Regular screenings for those with risk factors may aid in early detection and management.
When to Seek Professional Help
Persistent or worsening bone pain.
Unexplained swelling or lumps in soft tissues.
Any new or unusual symptoms post-remission should be evaluated.

Tips for Medical Coders
Ensure correct distinction between solitary plasmacytoma in remission (C90.31) and active disease codes.
Verify documentation for the specific location and remission status.
Avoid coding as multiple myeloma unless documentation explicitly confirms its progression.
